Description

  The present invention is based on the fact that when an occupant's body is fixed by various child seats or other restraining belts due to inertia due to a car accident or sudden braking, the unrestrained head moves forward due to inertia. The present invention relates to an impact reducing device for a neck by a cushion of a flexible material and a method thereof for the purpose of relaxing an excessive burden on the neck of the neck.

  When the body is completely fixed with various child seats and other restraining belts, the forward movement of the head is considerable due to inertia due to high-speed collision, especially for infants, children, and elderly people In some cases, the trachea and bones of the neck may be adversely affected depending on the type of restraint device and how it is worn.

  There are many types of child seat-related devices, efforts are made to eliminate various problems, and there are also excellent products. However, it is not 100% safe, but if innovation increases safety even by 1%, it will be implemented, and by repeating it, we believe that innovation will be made and better products will be developed. . However, it is not until the original prototype is made that it can be improved, and the importance of child seats and safety equipment as prototypes is not neglected.

Child seat types include bet-type child seats, rotating types, basic types, clothing-type child seats, and schoolchildren's chair types. Related equipment includes belt covers, cushioning cushions, nap sleeping cushions, nappa sleeping pillows, child necks. There is a cushion (see Non-Patent Document 1).
"Refer to AUTOBACS Group Child Seat Catalog 200404"

  When the occupant is fixed with various child seats or other restraining belts and the inertia of the accident is stopped by stopping the occupant's body, depending on the inertia of the head that is not restrained, depending on the device or the mounting method, An excessive burden is placed on the neck. In particular, when an infant or a young child is sleeping, it can be assumed that depending on the type of device and the wearing method, it is extremely difficult to stop the head from shaking due to inertia.

  Temporarily, the burden on the neck becomes excessive in the case of a frontal collision accident when traveling at 100 km / h on a highway.

  On the other hand, when a rear-end collision occurs, the rear-end collision of about 40 km may cause whipping, and recently, by installing a lashing prevention device on the upper part of the seat back, the whipping symptom is considerably lightened. Although it functions effectively as a whiplash prevention device, there are not many measures for moving the head forward.

  People tend to think that the concept of various child seats and other belts for restraining purposes is to sit at a right angle to the seat and stop in that state in the event of an accident, but the purpose of restraining devices such as child seats is the body, It is also important how to reduce the impact on the neck and head. In other words, the body and head at the time of an accident are prevented from being thrown out of the vehicle without touching the dashboard, etc., and the impact on the body and neck caused by various child seats and other restraining belts is reduced. However, the style at the time of wearing tends to seem to be the style at the time of restraint.

  If you stop at the occupant's boarding position in the event of an accident, most of the inertia will be received by the occupant's chest, the impact may be excessive, and the head is not structured to stop at that time. Speaking only to the part, the inertia that pulls forward is applied only to the head. In that case, there is a neck in the middle between the body restrained by various child seats and other restraining belts and the head that is not restrained, and the force of reverse lashing is applied to the neck. It may be too much for the weak young.

  With the structure of the prior art, depending on the type and mounting method of various child seats and other belts for restraining, the inertia may cause a shock to the neck during inertia, sudden braking, or sudden acceleration. Yes, in extreme cases, it compresses the trachea of the neck, and depending on the type of restraint and how it is worn, it may affect life. The purpose of various child seats and other restraining belts is not to fix the body completely, but to prevent it from being thrown out of the vehicle by slipping through the belt, etc., the head and body are dashboard, windshield, side door glass, handle It is to prevent direct contact with in-vehicle devices, and to moderate the impact on the body by various child seats and other restraining belts, and to prevent the belt from hanging on the neck, especially in the event of an accident It is important to reduce the burden on the neck.

  Various conventional child seats and other belts for restraining purposes focus only on restraining the occupant and few are intended to reduce the burden on the neck, or the effect May be difficult to expect.

  In the case of stopping an occupant's body fixed with various child seats or other restraining belts, or in the case of an accident during high-speed driving, an impact caused by excessive inertia is instantaneously received. In this case, the burden on infants and young people on the soft body and on the neck with weak restraining force may be too large.

  Depending on the nature of the accident, depending on the type of equipment and how it is worn, the body of an infant or young person may be pulled forward and the neck may tilt too forward. If the forward tilting force exceeds the limit, there is a possibility of slipping through the belt, and it is necessary to stop within the limit.

  In various child seats and other restraining belts, there may be a case where the impact becomes excessive when the face is covered by external pressure due to a crash accident or the like, and breathing cannot be easily performed.

  In order to reduce the inertia of the head that is not restrained when the body part of the occupant is fixed to the seat by the restraining equipment and the inertia due to the accident or sudden braking of the automobile is stopped, A flexible material that is attached to a non-moving part of a child seat or seat, and is configured to fit the head with a shape that makes both the chest and face contact when the body is pulled forward by inertia This is solved by a shock reduction device for the neck by using a cushion.

  According to claim 2, in order to reduce the inertia of the head that is not restrained when the body part of the occupant is fixed to the seat by the restraining equipment and stopped due to the accident caused by the car accident or sudden braking, Attached to a non-moving part of a child seat or seat, pushes the protruding part of the cushion with the pushing force by the body when the body is pulled forward due to inertia, rotates the cushion upward, and contacts both the chest and face Thus, the problem is solved by a method of reducing the impact on the neck by a cushion of a flexible material, characterized in that the head is configured to fit.

  According to a third aspect of the present invention, the seat back of various child seats, or only the inner part of the seat back leans forward or the seat part moves forward due to the force pulling the body forward due to inertia. With a structure that is designed to fit the chest and head in a flexible cushion that is attached to various child seats or non-moving parts of the seat. Resolve.

  According to a fourth aspect of the present invention, the seat back of various child seats or only the inner part of the seat back leans forward or the seat part moves forward due to the force that pulls the body forward due to inertia. With a flexible material cushion, which is structured so that the chest and the head can be accommodated by rotating upward the cushion of the flexible material attached to the non-moving part of various child seats or seats This is solved by reducing the impact on the neck.

  A fifth aspect of the present invention is the first and third aspects of the present invention, in which the shape of the cushion of the flexible material is a concave lens type, and an air intake is formed in the center portion, so When the cushion is pressed against the face, it reduces the force that compresses the face due to its shape and makes it easy to breathe even when pressed against the face. Resolve.

  A sixth aspect of the present invention relates to the second and fourth aspects of the present invention, wherein the shape of the cushion of the flexible material is a concave lens type, and an air intake port is formed in the center portion, so that the cushion of the flexible material can be obtained due to inertia during an accident or a crash accident. Solved by a method of reducing the impact on the neck with a cushion of flexible material, which reduces the force of pressing the face by its shape when it is pressed against the face and facilitates breathing even when pressing on the face To do.

  In order to reduce the inertia of the head that is not restrained when the body part of the occupant is fixed to the seat by the restraining equipment and the inertia due to the car accident or sudden braking is stopped, the chests inside the belts of various child seats A cushion of flexible material is sandwiched in the vicinity, the occupant moves forward due to inertia due to an accident, the chest and the belt press the vicinity of the chest of the cushion of flexible material, the shape is deformed by that pressure, or the fixed part is released The problem is solved by a shock-reducing device for a neck by a cushion of a flexible material, characterized in that it is configured to cover the face by changing the shape and reduce the excessive impact on the chest and face and the burden on the neck.

  In order to reduce the inertia of the head that is not restrained when the body part of the occupant is fixed to the seat by the restraining equipment and the inertia due to the car accident or sudden braking is stopped, the chests inside the belts of various child seats A flexible material cushion is sandwiched in the vicinity, the occupant moves forward due to inertia due to an accident, the chest and the belt press the vicinity of the chest of the flexible material cushion, and the shape is deformed by the pressure, or the fixed part The problem is solved by a shock-reducing method using a cushion of a flexible material, which reduces the excessive impact on the chest and face and the burden on the neck by covering the face by changing the shape.

  According to claim 1, in order to reduce the burden on the neck due to the inertia of the occupant, a cushion made of a flexible material is placed on the foot or installed on a restraining device placed on the foot, and various child seats and other It is attached to a belt for the purpose of restraining the body, and when the occupant's body moves forward due to inertia, a device that reduces the impact on the neck by bringing the cushion of a flexible material into contact with the body and face flatly, To reduce the burden on the neck. In addition, the child seat mounted on the upper part of the foot is fixed by an existing seat belt, and a cushion of a flexible material is attached to the child seat, thereby eliminating the conventional problem that is an impact on the face and neck. In other words, the problem can be solved by a new device that reduces excessive impact on the neck, which is a problem of various existing child seats and other belts for restraining purposes.

  The position at which various child seats and other restraint belts are locked due to an accident varies depending on the type of equipment, the occupant's body shape, the seat position, the reclining degree, and the wearing method, but the average angle at which the body tilts forward due to the inertia of the accident The value is set to 25 degrees forward and the head is placed in the cushion of the flexible material at that position. In addition, there is an auxiliary restraining effect even when the belt or the like is slipped by the centrifugal force to the left and right, and there is also an excellent new effect that supplements the conventional equipment. In other words, it is installed at a position where it does not get in the way during normal driving, and it is possible to reduce the impact on the neck with a cushion of flexible material only at the time of an accident, and by combining both comfort during driving and safety at the time of the accident, it is a conventional problem Solve the point.

  Moreover, as a case of a traffic accident, there can be assumed a case of a crash with no brake, a crash after a few seconds after stepping on the brake, a crash after just turning the steering wheel left or right or a few seconds later. In other words, in cases other than the collision with the above-described no-brake, the belt is locked at a position after the occupant's body tilts forward or is swung left and right. Therefore, on average, it was assumed that the stopping position by various child seats and other stopping belts was about 25 degrees forward tilt.

  There are bet type child seats, rotating type child seats, junior seats, clothing type child seats, school chair type, belts for other restraint purposes, etc., and various improvements, and further improvements. However, there is a certain amount of effect as it is. However, the impact reduction device to the neck by the cushion of the flexible material of the present invention can reduce the impact on the chest and the burden on the neck, and can further increase the effectiveness and reduce the excessive burden on the neck. The conventional problems can be solved.

  According to claim 2, when the inertia at the time of the accident is fixed to the seat and the occupant's body is restrained, the burden on the neck can be reduced if the head is also restrained at the same time. Therefore, a cushion made of a flexible material is attached to a position that does not interfere with normal driving, and the cushion's body moves forward due to inertia during an accident, pushing the protrusion of the cushion, the cushion rotates upward and the occupant's body rotates upward. By covering the face and chest flatly and reducing the forward inertia of the head, the burden on the neck is said to be reduced, and the protrusion of the cushion of flexible material is pushed and rotated upward The method solves the conventional problems by reducing the impact on the neck.

    The third aspect of the present invention is a structure in which the child seat or the inner part of the seat back of the child seat is tilted forward or moved forward due to inertia in the event of an accident. Both impacts are weakened and the impact on the body is reduced. Furthermore, by providing a cushion made of a flexible material at the stop position, the impact on the neck can be reduced by the planar contact between the chest and the face. In other words, the seat back or the inner part of the back is tilted forward or moved forward within a certain range due to accidental inertia, so that the cushion of the flexible material and the face and chest are in contact with each other in a plane, especially infants Relieve the impact on the neck of young people, etc., and solve the conventional problems.

  In other words, the impact on the body and neck caused by various child seats and other restraining belts in the event of an accident, and the impact to stop inertia by moving the seat and head to a position slightly ahead. Is dispersed in two steps to moderate the impact.

  In particular, when infants and young people are sleeping on the highway, they think that there is almost no maintenance of the ability to stand the infant's neck, and a cushion of flexible material for the purpose of protecting the neck in such a case This makes it possible to reduce the impact on the neck and solve the conventional problems.

  As a method of tilting the seat back forward, it is the reverse of the operating system of the spring-type reclining seat in the reception room, etc.In other words, if you sit back and push the back back backward with the force of the back, release the pressing force of the back Leave the back of the reclining seat back to the original backrest position, cut out the seat part, install a new seat on the rear side of the cut-out seat, sit on the new seat, fix the body to the backrest with a restraining device, and pull the seat backrest It is set to return when it is tilted forward and released. That is, it is possible by attaching a new seat behind the backrest. Further, in the case of moving only the inner portion of the seat back, the connection between the back and the back can be made by a spring type or accordion-like structure. In other words, the impact to the neck can be reduced by the cushion of the flexible material, and the conventional problems are solved.

  According to the fourth aspect of the present invention, the seat back of various child seats, or only the inside of the seat back is inclined forward due to excessive inertia or moved forward, and the cushion of the flexible material is applied by the force of moving forward of the body. By pushing the protruding part, the upper part of the cushion rotates upward with the lower part of the cushion as a fulcrum, and the chest and face of the occupant are covered flatly, enabling the impact to the neck by the cushion of flexible material, Solve conventional problems.

  According to the fifth aspect of the present invention, the cushioning material made of a flexible material is made into a concave lens type, so that the impact on the face is softened. Further, by making a plurality of holes, the seat portion crashes and the cushioning material made of the flexible material comes into contact with the face. In this state, even if the body cannot move, breathing is possible with a shock-reducing device for the neck using a cushion made of a flexible material, which solves the problems of the prior art.

  According to the sixth aspect of the present invention, the flexible material cushion is formed as a concave lens type, and a plurality of holes are formed, so that the method can relieve the impact and can breathe even when the face is covered. Solve the point.

  According to the seventh aspect, a cushion is sandwiched between chests of various child seats, and is simply fixed by a belt. When the occupant moves forward due to inertia at the time of the accident, a part of the cushion of flexible material is compressed with the chest and belt, and the cushion of flexible material that is simply fixed is deformed to cover the occupant's face and chest This reduces the impact on the chest and neck, protects infants and young people with low neck stability, enables cushioning with a flexible material to reduce the impact on the neck, and solves the conventional problems. Furthermore, if the shape of the cushion is a concave lens type and a hole is made in the part that hits the face, the impact on the neck will be more gradual, and even if the car crashes and the face is covered with the cushion, breathing is possible, conventional technology Solve the problem.

  According to the eighth aspect of the present invention, the cushion sandwiched between the chests of various child seats changes the shape of the cushion or the cushion by the force of the occupant's body moving forward due to inertia and the force of stopping the force The conventional method is solved by reducing the impact on the face and the excessive burden on the neck by the operation method of covering the face by removing the stop portion. Furthermore, by making the shape of the cushion a concave lens type and making a hole in the part that hits the face, the impact on the neck becomes more gentle, allowing breathing even if the car crashes and the face is covered with the cushion, Solve technical problems.
